'''OpenGL extension EXT.texture_format_BGRA8888
This module customises the behaviour of the
OpenGL.raw.GLES1.EXT.texture_format_BGRA8888 to provide a more
Python-friendly API
Overview (from the spec)
This extension provides an additional format and type combination
for use when specifying texture data. The current allowed combinations
are:
Internal Format External Format Type Bytes per Pixel
--------------- --------------- ---- ---------------
RGBA RGBA UNSIGNED_BYTE 4
RGB RGB UNSIGNED_BYTE 3
RGBA RGBA UNSIGNED_SHORT_4_4_4_4 2
RGBA RGBA UNSIGNED_SHORT_5_5_5_1 2
RGB RGB UNSIGNED_SHORT_5_6_5 2
LUMINANCE_ALPHA LUMINANCE_ALPHA UNSIGNED_BYTE 2
LUMINANCE LUMINANCE UNSIGNED_BYTE 1
ALPHA ALPHA UNSIGNED_BYTE 1
This table is extended to include format BGRA_EXT and type UNSIGNED_BYTE:
Internal Format External Format Type Bytes per Pixel
--------------- --------------- ---- ---------------
BGRA_EXT BGRA_EXT UNSIGNED_BYTE 4
RGBA RGBA UNSIGNED_BYTE 4
RGB RGB UNSIGNED_BYTE 3
RGBA RGBA UNSIGNED_SHORT_4_4_4_4 2
RGBA RGBA UNSIGNED_SHORT_5_5_5_1 2
RGB RGB UNSIGNED_SHORT_5_6_5 2
LUMINANCE_ALPHA LUMINANCE_ALPHA UNSIGNED_BYTE 2
LUMINANCE LUMINANCE UNSIGNED_BYTE 1
ALPHA ALPHA UNSIGNED_BYTE 1
This format is renderable in versions of OpenGL ES from 2.0 onwards.
The official definition of this extension is available here:
